Set-Variables.ps1 script Unexpected token '?' in expression or statement
Describe the bug
When running the Set-Variables.ps1 script, I get the following error:
PS C:\dev\CodeSamples\TasksTracker.ContainerApps> .\Set-Variables.ps1 At C:\dev\CodeSamples\TasksTracker.ContainerApps\Set-Variables.ps1:74 char:41
- "Write-Host
"Set $i variable$($i -eq 1 ? '' : 's')."" | Out-File -F ... -
~
Unexpected token '?' in expression or statement. At C:\dev\CodeSamples\TasksTracker.ContainerApps\Set-Variables.ps1:76 char:43
- Write-Host "
nWrote $i variable$($i -eq 1 ? '' : 's') to $file.n" -
~
Unexpected token '?' in expression or statement. + CategoryInfo : ParserError: (:) [], ParseException + FullyQualifiedErrorId : UnexpectedToken
I am not particularly familiar with PowerShell, but I have tried to adjust the quotes, etc. in those commands, but to no avail. Would you mind offering me some guidance please?
Expected behavior
From the workshop instructions: "Execute the script. You will do this repeatedly throughout the modules. The output of the script will inform you how many variables are written out."
Actual behavior
As per the description:
At C:\dev\CodeSamples\TasksTracker.ContainerApps\Set-Variables.ps1:74 char:41
- "Write-Host
"Set $i variable$($i -eq 1 ? '' : 's')."" | Out-File -F ... -
~
Unexpected token '?' in expression or statement. At C:\dev\CodeSamples\TasksTracker.ContainerApps\Set-Variables.ps1:76 char:43
- Write-Host "
nWrote $i variable$($i -eq 1 ? '' : 's') to $file.n" -
~
Unexpected token '?' in expression or statement. + CategoryInfo : ParserError: (:) [], ParseException + FullyQualifiedErrorId : UnexpectedToken
Reproduction Steps
Just run the script in the latest (or any I think) version of PowerShell.
Hi @henrydyer, I just followed our instructions and see the output, as expected, as Wrote 1 variable to ./Variables.ps1. I run PowerShell 7.4.1.
Could you double-check your steps, please, and inform us what PowerShell version you are using?
Hi Simon, thanks for getting back to me so quickly! Here’s my version info: Name Value
PSVersion 5.1.19041.4046 PSEdition Desktop PSCompatibleVersions {1.0, 2.0, 3.0, 4.0...} BuildVersion 10.0.19041.4046 CLRVersion 4.0.30319.42000 WSManStackVersion 3.0 PSRemotingProtocolVersion 2.3 SerializationVersion 1.1.0.1
It was doing the same before I upgraded though. I can’t recall the exact version I had previously, but it was 4.x.x. My first thought was that I needed to update PS.
I just re-copied the code for the script and tried again. It’s odd that it seems to have no issue running the actual variable setting part, but just struggles with formatting the output.

Hi @henrydyer, you are welcome! I'm so sorry you are running into trouble there. I have fairly exclusively run this on PowerShell 7 in Windows 11, so I can't speak to 5.1 on Windows 10 much. Given that this seems to revolve around an informative console output only and perhaps not the core functionality, could you try to comment it out and see if everything else from there on goes as desired, please? If you are so inclined, I would also love a PR if you tinker with the output and get it working.
Thank you!
Hi Simon, no worries! I have made some progress in that I can run the script from the VS Code terminal without issue, it just doesn’t work from a standalone PS terminal window.
The output I get in the Code terminal is “Wrote 1 variable to ./Variables.ps1.”, and it generates the following in Variables.ps1:
Execute with "./Variables.ps1" to restore previously-saved variables.
Set-Variable -Scope Global -Name TODAY -Value (Get-Date -Format 'yyyyMMdd') Write-Host "Set 1 variable."
I assume this is correct, as none of the other variables have actually been set yet.
So it sounds like my issue is just down to version incompatibilities. If I make any other discoveries, I’d be happy to raise a PR of course.
Thanks for your help.

Hi @henrydyer, awesome progress!
It looks like you are running into a difference between Windows PowerShell built on .NET Framework and the open-sourced PowerShell built on .NET Core. It appears that your VS Code is using the newer PowerShell version via its extension.
I typically use Windows Terminal and PowerShell in my setup. Not to get too much beyond the filed issue, but it may be worthwhile for you to explore whether that setup could provide some advantages.
I'll keep the issue open, but I don't expect to do any active development on it as it's a relatively benign issue, all-in-all, and a work-around exists. I thank you for filing it, and I hope that you enjoy working with Azure Container Apps! Reach out if you have any questions, please.
OK, thanks very much!
